I have some code that uses the module Big_int
, like in:
open Big_int;;
Big_int.gcd_big_int 5 6;;
However, when I compile this with utop dune utop --release
(I use release
to avoid some warnings), then I get this error:
Error: Required module `Big_int' is unavailable
I have read about it and I have read (https://groups.google.com/g/felix-language/c/1CfHgpe9zps?pli=1) that 'Big_int is no longer part of the OCaml distribution. It was replaced by Zarith'. Well, I know that, but also that I can still use Big_int
.
How do I know it? The point is that if I start utop
with any other file that has no errors, and once inside I open Big_int
, then it does not regret:
utop # open Big_int;;
Once there, it autocompletes my Big_int.
, like in Big_int.add_big_int
. So there Big_int
is there somewhere and it is recognised (VSCode also autocompletes it).
There is something I am not understanding. Any help?
